Quick answer: Unplug it and hold the power button until it switches off — right now, even if it still seems fine. Unplug USB devices, tip it upside down in a tent shape so liquid drains away from the board, and blot what you can. Then don’t switch it back on to check. The battery keeps the board live, so corrosion keeps working even when the laptop is off. Get it opened and cleaned the same day if you can. Updated November 2026.
A glass of water knocked over at your desk, kopi in a crowded café, a toddler with a cup of Milo. Laptop spills happen in seconds, and what you do in the next hour decides whether it’s a cheap clean or an expensive board repair. Here’s exactly what to do.
The First 5 Minutes
- Unplug the charger. Power plus liquid is what causes a short circuit.
- Hold the power button for 10 seconds until it switches off. Don’t wait to save your work — a few seconds of power through wet circuits can burn a chip.
- Unplug everything: USB drives, mouse, dock, SD card.
- Turn it upside down with the lid open in a tent shape (an upside-down V) on a towel, so liquid runs out of the keyboard instead of deeper inside.
- Blot, don’t wipe. Use a dry cloth or paper towel on the keyboard and surfaces. Wiping spreads the liquid.
Got a removable battery? Take it out now. Most modern laptops and every MacBook have the battery inside, which is why the next steps matter.
What Not to Do
| Don’t | Why |
|---|---|
| Turn it on to “check” | The most common way a cheap clean becomes a board repair. Power through wet circuits causes shorts. |
| Charge it | Same reason — and the charging circuit is often the first part to fail. |
| Put it in rice | Rice can’t draw liquid out of a closed laptop, and the starch dust gets into ports and fans. |
| Use a hairdryer | Heat can warp parts and spreads moisture further in. It doesn’t remove the residue that causes corrosion. |
| Shake it hard | It pushes liquid deeper rather than out. |
| Wait a week for it to dry | The water evaporates, but the minerals, sugar and salts stay on the board and keep corroding it. |
The First Hour: Why Drying Isn’t Enough
Most people assume that once the laptop is dry, it’s safe. It isn’t. The danger isn’t the water — it’s what’s left behind. Tap water carries minerals, and coffee, tea, juice and soft drinks add sugar and acid. Together with Singapore’s humidity, that residue causes corrosion on the board over the following hours and days.
That’s why a laptop can seem fine after a spill, then die a week later. The only reliable fix is opening it, disconnecting the battery and cleaning the board in an ultrasonic cleaner to remove the residue.
Does It Matter What You Spilled?
| Liquid | Risk | Notes |
|---|---|---|
| Plain water | Lower | Still conducts electricity and leaves minerals — still needs cleaning. |
| Coffee or tea with sugar or milk | High | Sticky residue gums up keys and corrodes contacts quickly. |
| Soft drinks, juice, Milo | High | Sugar and acid — corrosion sets in fast. |
| Beer or wine | High | Sugar plus acid, and sticky when dry. |
| Sea water or soup | Very high | Salt is highly conductive and corrosive. Treat as urgent. |
How Bad Is It? What Your Laptop Is Telling You
- Small splash on the keyboard, laptop off quickly: often just a clean, sometimes a keyboard replacement.
- Sticky or dead keys: liquid under the keyboard. The board underneath may also need cleaning.
- Won’t turn on: liquid reached the power circuits. Usually a clean plus board-level repair — see laptop won’t turn on.
- Screen lines, flicker or no picture: liquid on the display cable or graphics circuit.
- Was on for a long time after the spill: expect more board damage; bring it in as soon as possible.

MacBook Spills
MacBooks have the battery glued inside and liquid usually goes straight through the keyboard to the logic board. Shut it down with the power button (hold for 10 seconds), unplug it and tent it upside down. On Apple Silicon MacBooks the data is tied to the board, so getting it cleaned before corrosion spreads also protects your files. See MacBook water damage repair.
Will I Lose My Files?
Usually not. A spill rarely damages the storage itself, and a board that is cleaned in time can normally be repaired with the data intact. If the board can’t be saved, data recovery is often still possible. If the laptop still works after a spill, back up straight away.
Frequently Asked Questions
My laptop still works after a spill. Is it okay?
Not necessarily. Corrosion can take days to show. Switch it off, back up when it’s safe to, and have it checked — a clean now is far cheaper than a board repair later.
Should I put my laptop in rice?
No. Rice can’t draw liquid out of a closed laptop and leaves starch dust inside. Tent it upside down and get it opened and cleaned instead.
How long should I wait before turning it on?
Don’t rely on waiting. The water evaporates but the residue stays and corrodes the board. Have it opened and cleaned before you power it on.
Does warranty cover laptop spills?
Standard manufacturer warranties exclude liquid damage. Some accidental damage plans (like AppleCare+ or a brand’s accidental damage cover) do include it — check yours first.
